Present study was carried out during 2019 at the Vegetable Research Farm, Punjab Agricultural University, Ludhiana to generate information on diversity of invertebrates in okra. Study revealed that okra crop was harboured by 27 invertebrate species belonging to 11 orders and 26 families. Of these, maximum belonged to order Hemiptera followed by Coleoptera. Higher values of Shannon-Wiener index (1.75, 1.84) and Simpson’s index (0.26, 0.17), respectively were recorded for both phytophagous arthropods and predators in untreated control plots. This is followed by neem/ other insecticides treated plots. Imidacloprid lowered the arthropod population. Occurrence of predators and phytophagous arthropods revealed a significant positive correlation with temperature (r=+0.37 to +0.99) and relative humidity (r=+0.04 to +0.80) except for few hemipterans and coleopterans.

Investigation to manage rodent pests in wheat crop sown with different tillage methods was conducted. The results revealed maximum efficacy in the form of control success (%) on plain bait consumption and burrow count basis with conventional (92.30) followed by zero tillage (84.74) and maize residue tillage (74.38). In these, rodenticide treatments with double burrow baiting was followed by single paper baiting. Lesser % cut tillers (0.39-0.53) and damage 9.56-15.71 kg/ 0.4 ha were observed in these. Burrow count in maize residue and zero tillage was 2.15 and 1.60x more than conventional tillage. Thus, rodenticide treatments with double burrow baiting at vegetative stage in December (bromadialone followed by zinc phosphide at 15 days interval) along with paper baiting (bromadialone) at reproductive stage (end February to 1st week of March) can be recommended against rodents in wheat crop to get higher economic returns (Rs.452.36-556.81/ 0.4 ha).
